The 13th is mountain climbing day
The 13th of every month is mountain climbing day 登山の日. Officially the full name is Ishii sports mountain climbing day. Ishii are the company that established the anniversary and they continue to support it by sharing tips, safe climbing practices, and inspire beginners to try hiking or mountaineering, every month.
The date comes from the wordplay “to‑zan” (とざん = mountain climbing), which sounds like 10‑3, making the 13th a fitting monthly reminder to enjoy the outdoors. The purpose of this day is to encourage people of all ages and skill levels to experience the beauty of Japan’s mountains throughout the year.
Its a day to connect with nature, and appreciate the seasonal landscapes, while discovering the physical and mental benefits that come from spending time in the mountains. However, with the increase in bear sightings and bear related incidences in recent years, please do take extra care if climbing mountains this year.

Former nickname was "Saitama". Changed it to save confusion on place review posts! Irish, 20+ years in Japan! I also write on my personal website: insaitama.com
